From the Star Tribune:
The boy disappeared when a therapist took him and other patients out of the hospital's locked pediatric psychiatric unit to go for a swim at a nearby pool. He was later found shoeless and in his hospital scrubs a mile away, on the Franklin Avenue bridge. A hospital courier spotted him after being alerted along with all other hospital staff to the disappearance. The driver had the boy in a headlock while waiting for officers to arrive, according to a police report.
The incident is the latest in a series of controversies regarding behavioral health at the university's primary teaching hospital, including allegations of coercing patients into research, that have resulted in new leadership and ethics policies.
Medicare's investigators pointed out the ease with which a therapist took the boy from his unit, just two days after he was found in his hospital room with a sweatshirt stuffed down his throat and a blanket wrapped around his neck.
Perhaps the most revealing sentence in the article is this one. "Fairview determined that it wasn't required to conduct an analysis of this event because a review is mandated only if a patient disappearance results in a death or severe injury. The incident consequently won't show up in the state's tally of adverse events."
